(UPDATED: Complete participation report attached at bottom of this post)

Two notable starters are not participating in practice today: cornerback Tarell Brown (knee) and wide receiver Mario Manningham (shoulder). Each player was doing individual conditioning in the team’s new weight room.

Cornerback Chris Culliver, who’d be in line to start ahead of Brown, suited up for practice but was feeling ill and left the field during warmups.

Linebacker Aldon Smith again is wearing a no-contact jersey because of a lingering shoulder injury.

Rookies A.J. Jenkins and LaMichael James wore their own jerseys for what seemed like the first time all season, as they’ve typically suited up in an opponent’s number for scout-team purposes.
